Specification of Letters Patent.

Zacatented Ivay 8, 1906.

Application filed February 6. 1906. Serial No. 299,715.

To a/ZZ whom it' rma/y concern.: i

Be it known that I, AUGUSTUS LEIOESTER MOSS, a citizen of the United States, and a resident of Sandusky, in the county of Erie and State of Ohio, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.

The object ofthe invention is to provide a new and improved valve, more especially designed as a controllervalve or checkvalve, for controlling the passage of compressed air or other iluid and when closed being capable of holding a fluid-pressure, exceeding, say, Sixty or seventy pounds, for a long period and without danger of leakage, thus rendering the valve exceedingly eiiicient for use in pneumatic sanding devices for automobiles and the like and such as shown and described in the Letters Patent of the United States, No. 807 ,186 granted to me December 12, 1905.

The invention consists of novel features and parts and combinations of the same,

which will be more fully described hereinaf-- ter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying draw-.

ings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation ofthe improvement arranged as a controller-valve for controlling the Huid-pressure Jfrom the air reservoir lor pump to the sanding-distributer. Fig. 2 is a plan view ofthe same. Fi 3 is a transverse section of the same on the Iine 3 3 of Fig. 1. Fig. 4 is a plan view of the valve proper. Fig. 5 is a like view of the rubber gasket for the valve, and Fig. 6 is a longitudinal central section of the improvement arranged as a check-valve between the airreservoir and the sandin -distributen The valve-casing A (iIlustrated in Figs. 1, 2, and 3) is provided with a chamber B, provided at one side with an inlet C, connected with the air-compressor or air-pump, and on the other side of the said chamber is arranged an inlet D, connected with the air-reservoir charged with air from the ump by way of the said chamber B. A va ve-seat E within the chamber B connects the latter with an outlet F, formed on the casing A and connected with the sand-distributer, and the said valve-seat E is adapted to be closed by a valve G, carrying on its valve-disk a rubber gasket H, seated at one face in an annular I groove formed on the valve-disk and seated at its other Opposite face in an annular groove formed in the wall of the valve-seat E.

The under side of the valve G is pressed on by a spring I, extending in the chamber B and resting on a plug J, screwing in the bot tom of the chamber for closing the same. The spring I is suiiticiently heavy to properly hold the gasket H firmly seated to prevent leakage of air from the chamber B by way of the valveseat E into the outlet F, leading to the sand-distributer. The stem G' of the valve G extends through a suitable bearing A' on the casing A to the outside thereoi?, and the outer end of this valve-stem G' is engaged by a lever K, connected by a link L with a hand-lever or other means under the control of the operator for imparting a swinging motion to the lever K, so as to press the valve-stem G' to move the valve G oi its seat whenever it is desired to establish communication between the chamber B and the outlet F, leadingto the sand-distributer. As soon as the pressure on the hand-lever mentioned is released then the valve G is immediately seated by the action of the spring il to disconnect the chamber B from the outet F.

In the modiiied form shown in Fig. 6 the valve-casing A2 is provided at one end with an inlet D', connected with the air reservoir, pump, or like Source of compressed-air supply, and the other end of the casing A2 is provided with an outlet F', connected with the sand-distributer, the outlet F' being in the form of a plug F2, screwing into the end of the casing A2. A valve-seat E' extends trans versely in the casing A2 and on it is adapted to be seated a valve G2, having a rubber gasket H' and pressed on by a spring I', held on the plug F2. The stem G3 of the valve G2 i's mounted to slide in a suitable guideway A3, arranged within the casing A2. By the arrangement described the valve G2 is firmly held to its seat by the pressure of the spring I' and all leakage between the inlet'D' and the outlet F' is prevented by the gasket H' being seated partly in an annular groove in the valve G2 and partly in an annular groove in the valve-seat E', the same as above described, and shown in Fig. 3.

By the arrangement described undue leakage of air is prevented, so that a heavy pres- Sure can be maintained in the air-.reservoir for a long time without danger of leakage, thus rendering the valve exceedingly service- IOO IIO

able for pneumatic sanding devices, as above referred to.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A valve comprising a valve-casing having an inlet for connection with a pressuresupply and an outlet for the discharge of the fluid-pressure, a valve-seat in the said valvecasing between the inlet and outlet, the said valve-seat having an opening and an annular groove, a bearing on the said valve-casing, a valve-disk having a stem engaging the said bearing, the said valve-disk having an annular groove registering with the said valve-seat groove, a rubber gasket iitting the said registering grooves, and a. spring pressing the said valve-disk.

2. A controller-valve for pneumatic sanding devices, comprising a valve-casing having a chamber, inlets, of which one is connected with an air-compressor and the other with an air-reservoir, an outlet on the said valve-casing, a valve-seat between the said chamber and the said outlet, a valve proper within the said chamber and adapted to be seated on the said valve-seat, the stem of the valve extending to the outside of the said valve-casing, a spring within the said chamber and pressing the said valve proper to hold it to its seat, and manually-controlled means engaging the outer end ofthe said valve-stem for moving the valve oii its seat against the tension of its spring.

3. A controller-valve for pneumatic sanding devices, comprising a valve-casing having a chamber, inlets, of which one is connected with an air-compressor and the other with an air-reservoir, an outlet on the said valvecasing, a valve-seat between the said cham- 4o ber and the said outlet, a valve proper Within the said chamber and adapted to be seated on the said valve-seat, the stem of the valve eX- tending to the outside of the said valve-casg, a spring within the said chamber and pressing the said valve proper to hold it to its seat, a plug for closing the said chamber and supporting the said spring, and manually- 'controlled means engaging the outer end of the said valve-stem for moving the valve off its seat against the tension of its spring.

4. A controller-valve for pneumatic sanding devices, comprising a valve-casing having a chamber, inlets, of which one is connect- -ed with an air-compressor and the other with an air-reservoir, an outlet on the said valvecasing, a valve-seat between the said chamber and the said outlet, a valve proper within the said chamber and adapted to be seated on the said valve-seat, the stem of the valve extending to the outside of the said valvecasing, the said valve proper having a valvedisk and a rubber gasket fitting with one face into an annular groove in the valve-disk and fitting with the opposite face an annular recess in the said valve-seat, a spring within the said chamber and pressing the said valve proper to hold it to its seat, and manuallycontrolled means engaging the louter end of the said valve-'stem for moving the valve off its seat against the tension of its spring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
